Bifunctional enzyme which has both oligoribonuclease and pAp-phosphatase activities. Degrades short RNA and DNA oligonucleotides with a length of up to 33 nucleotides, although the enzyme is most active on shorter substrates, in a 5' to 3' direction. Converts 3'(2')-phosphoadenosine 5'-phosphate (PAP) to AMP, has very low activity on cAMP and cGMP.
